UNIVERSAL ROLLING-MILL.

SECIFIOATION forming part of Letters Patent No. 684,658, dated October15, 1901,

Application tiled November 21, 1900. Seria] No. 37,255. (No model.)

To all whom it may concern:

Bc it known that I, PETER M. IVEBER, a citizen of the United States ofAmerica, residing at Homestead, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Im provements inUniversal Rollingdtlills, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inrolling-mills, and is an improvement upon my Patent No. 645,409, bearingdate of March 13, 1900.

The present invention has for its object to construct a universal millwherein the horizontal and vertical rolls are adjustable and providemeans whereby the horizontal will impart or communicate a rotarymovement to the vertical rolls; furthermore,provide means whereby thehorizontal rolls will be connected at all times to the vertical rollsirrespective to any adjustment of said rolls.

In my former patent I have shown a pair of horizontal and verticalrolls; but the vertical rolls were driven by the f rictional engagementof the blank to be rolled, and I find that a great advantage is obtainedby connecting means to the horizontal rolls that will impart a constantrotary movement to the vertical rolls.

Another object of my present invention is to provide means whereby aperfectly smooth beam or the like may be rolled with less friction thanheretofore and preventing any liability of the vertical rolls stoppingin case a great pressure is bearing against them when the same aredriven by frictional engagement.

Ihave found by the use of myimprovements there will be less wear andtear of the working parts of the machine. Consequently the lifetime ofthe same will beprolonged in this manner.

W'ith the above and other objects in view the invention consists in thenovel combination and arrangement of parts to be hereinafter more fullydescribed, and specifically pointed out in the claims.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, andwherefin like numerals of reference indicate correspending partsthroughout the several views, in which- Figure l is a side elevation ofmy improved universal mill. Fig. 2 is a front view thereof. Fig. 3 is aside elevation of thc vertical and horizontal rolls, lthe latter beingpartially broken away. Fig 4 is an underneath plan view of the verticalroll.

In the drawings, the reference-nunieral l represents the housings, 2 theupper horizontal roll, and 3 the lower horizontal roll, the latter rollbeing provided with cog-wheels 4 on each side thereof, said cog-wheelsbeing adapted to mesh with the cogs 5 of the vertical rolls 6, said cogs5 being arranged on the under face of said rolls 6 and extendingradially around the periphery of said rolls, said horizontal andvertical rolls being adjustable for the purpose of rolling differentthicknesses of beams.

The operation of my improved rolling-mill is as follows: The horizontalrolls 2 and 3 being driven in the usual and well-known manner, the lowerroll 3, carrying with it the c0g wheels 4, will communicate a directrotary movement to the vertical roll 6, the latter being driven inunison with the rolls 2 and 3 as the blank is formed between thehorizontal and vertical rolls.

The many advantages obtained by the use of my improvements willbereadily apparent from the foregoing description and by referring to theaccompanying drawings.

Particular attention is directed to the fact that the arrangement asherein described may be attached to the upper roll instead of the lowerone and may be operated in the same manner; furthermore, that othermeans may be employed carried by one or both of the horizontal rolls tocommunicate a direct rotary movement to the vertical rolls and thatother changes may be made in the details of construction withoutdeparting from the general spirit of my invention, and the verticalrolls are adjusted inwardly and outwardly, as shown in the drawings.

In the drawings of my prior patent, as well as the present invention, Ihave shown the vertical rolls constructed in a plain cylin- IOO driealform; but I do not wish to limit myself to this construction, as thesame may be mountedV upon bearings or shafts when desired. It Will alsobe noted that the horizontal rolls maybe adjusted upwardly anddownwardly, either one roll or the other roll, as may be found mostexpedient.

Having thus fully described. my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In a universal rolling-mill, the combination of horizontal adjustablerolls, vertical adjustable rolls, oog-wheels arranged to one of saidhorizontal adjustable rolls, cogs arranged upon one end of each of thesaid vertical adjustable rolls to comm unieate a rotary
